I'm William and this is my school project on sources of energy.

Most people get electricity from:

• coal
• oil
• gas

They aren't renewable and they make air and water dirty. My family thinks looking after our planet is important. We should save energy and we should also use 'renewable sources of energy. Read on to learn more.

2. wind farms use the wind to make energy. This energy turns into electricity and we can use it to power our washing machines and blenders. Wind is always with us, so we can use it again and again. That's why we call it renewable.

Another thing we can use is the sun. Lots of houses have 3. solar panels on the roof. We can use the heat from the sun for water heating, but we can also make electricity with the sun's energy. 4. solar farms can make electricity for whole towns.

A block of flats is a tall building. We can build houses and flats with natural materials like wood and stone, so they are good for the planet. We can even grow plants on buildings. They look nice and the rooms inside stay warm in winter and cool in summer. That means less coal, oil and 5. gas for heating and we save energy.
